Question

Which of the following is an undifferentiated cell?

• A. Foetal cells
• B. Zygote
• C. Blood cells
• D. Neurons

Answer 1

The correct option is B

Zygote

Our body develops from a single cell called a zygote. The zygote is an undifferentiated cell. It then undergoes continuous divisions to form the foetus. Foetus has different cells with various structure and functions. The foetal cells are partially differentiated. These cells undergo complete differentiation from being stem cells to form specialised cells like blood cells, nerve cells, etc.
